US 2023/0056002 A1 · DISPLAY DEVICE AND MANUFACTURING METHOD OF THE SAME

Abstract

A display device includes a display panel including a display area in which a plurality of pixels is disposed and a bending area bent from the display area, a polarizing layer disposed on the display panel and a light-blocking film layer disposed under the display panel, where an entirety of an upper surface of the light-blocking film layer directly contacts a lower surface of the display panel in the display area, and an area of a lower surface of the light-blocking film layer is smaller than an area of the upper surface of the light-blocking film layer.

Dependent claims

A display device comprising:

a display panel comprising:
a display area in which a plurality of pixels is disposed;
and
a bending area bent from the display area;
a polarizing layer disposed on the display panel;
and
a light-blocking film layer disposed on a first surface the display panel,
wherein an entirety of a first surface of the light-blocking film layer facing the display panel directly contacts an entirety of the first surface of the display panel in the display area, and an area of a second surface of the light-blocking film layer opposite to the first surface of the light-blocking film layer is smaller than an area of the first surface of the light-blocking film layer.

A manufacturing method of a display device, the method comprising:

forming an align mark in a dummy area of a mother substrate comprising a display panel area comprising a first area in which a plurality of pixels is disposed and a second area adjacent to is the first area, and the dummy area adjacent to a side of the display panel area;
disposing a pre-polarizing layer on the mother substrate to cover an entirety of a first surface of the mother substrate in the first area;
disposing a pre-light-blocking film layer on a second surface the mother substrate opposite to the first surface of the mother substrate to cover an entirety of the second surface of the mother substrate in the first area;
cutting the mother substrate, the pre-polarizing layer, and the pre-light-blocking film layer along a cutting line which is a boundary between the display panel area and the dummy area to form a display substrate including the plurality of pixels and a dummy substrate including the align mark;
and
inspecting a cutting defect by imaging the align mark.
